Converting mkv to mp4 with `ffmpeg`

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

Data Types in Go

Go is a statically-typed language, which means that every variable has a specific data type that determines the kind of value it can hold. Go has several built-in data types that are categorized into four main groups: basic types, aggregate types, reference types, and interface types.

Basic Types

Basic types are the primitive data types in Go. They include:

Are you having a trouble about SEO Meta in server while your project is SPA only like React Router or Vue Router?

Can i guess you also don't have so much time for migration on the new framework that can handle server side rendering out of the box like Next.js, Nuxt.js, Gatsby, etc.

Setting the SEO meta in server like <title>, <meta name="description"/> are actually useful for search engine, and also good for showing your summary content in social media app by pasted the full url in Whatsapp, IG, Twitter, etc.

Enough the intermezzo, here we go.

The concept is actually simple, modify the index.html (from bundled source) before it served to the client.
